Problem with ports > COM9

[Gerd Staudenmaier]

Hi,

When installing both a PCMCIA serial interface card and the Widcomm
Bluetooth stack on my Acer laptop, WindowsXP assigned COM ports above
COM9 to both the card and the virtual serial bluetooth COM ports.

When trying to open such a two-digit COM port via calling
hPort = CreateFile (...)
I get back a NULL handle. Also ready-made code such as Hyperterminal was
not able to open that ports.

I was able to assign COM4 to the serial PCMCIA card and then the same
code runs as should.
But I was unable to also assign single-digit COM ports to the emulated
Bluetooth COM ports.

Does anyone know of a workaround to make two-digit COM ports work or
have an idea on how to change the default COM port assignment for the
Widcomm stack?

Regards, Gerd
